Add datalayer consent mode for loading scripts true Google Tag maanger

I think the best way to use a wp plugin as cooky bar that it injects a data layer with the cooky categories that are given consent for.
That way in GTM I can use that data layer trickers to fire or not.
see this example: https://www.webtoffee.com/how-to-attain-gdpr-compliance-by-using-google-tag-manager/?unapproved=182405&moderation-hash=41a8d4f9c5141b0663fb12c37c7ad32b#insert

Is this possible with your solution? in free or paid version?
